The Servomotor actuator from Polytherm is an ideal actuator for those with underfloor heating systems. This actuator is normally closed, noiseless and maintenance free.

This Actuator is Patented 100% protection against leaky valves meaning that it will not leak if installed properly. There is a All around function indicator to show when it is closed and has a high functional safety and a long expected service life. The power consumption of this unit it low and comes in 230 volts. This Actuator is easily installed and the adaption of the actuator can be checked via the valve

Currently the valve is controlled with Polytherm 2011821583113 clip on. Does your product replace my clip on servomotor and will your product fit?
Thanks

This actuator is 30mm Dia thread and 230V - main comparison points.
We have reached out to the manufacturer and Polytherm did not recognise the quoted reference no 2011821583113. Does it have another code and also can you send us a photo.
